For Use at Low-temperature
When utilizing conveyor chains at low-temperature such as within a refrigerator or in the cold ambiance, the following circumstances may possibly happen.
1) Minimal temperature brittleness
On the whole, a material is embrittled at low-temperature and shock resistance is lowered. This phenomenon is known as low-temperature brittleness, and the degree of embrittlement differs from material to materials.
The support limit of the conveyor chain relies on its specs.
two)Influence of freezing
At low-temperature, bending failure, roller rotation failure, fixing of chain, and so on. could be brought on by the freezing of penetrated water or deposited frost while in the clearance among pins and bushings, bushings and rollers or inner plates and outer plates. These disorders lead to an overload to act to the chain and drive, diminishing the daily life of your chain.
To prevent freezing, generally, it really is encouraged to fill the clearances which has a low-temperature lubricant suitable for the service 
temperature to avoid water, frost, and so forth. from penetrating the respective portions on the chain. For lubrication, a silicon based mostly grease is recommended.
For Use at High-temperature
Chains strength is diminished by high-temperature atmosphere, direct conveying of high-temperature loads, or radiated heat, and so forth. The services restrict at high-temperature depends not about the temperature on the services atmosphere but the temperature and materials in the chain body.
Following situations may possibly arise when chains are employed at high-temperature:
one) High temperature brittleness and fracture by lowered hardness of heat handled material
two) Brittleness induced by carbide precipitation
3) Abnormal dress in by scale
four) Fatigue fracture triggered by repeated thermal shock (cooling and growth)
five) Abnormal put on on account of an increase in the coefficient of friction
six) Creep fracture
7) Fracture because of thermal fatigue of welded spot
8) Effects triggered by thermal expansion
?Stiff hyperlinks and rotation failure as a consequence of decreased clearance ?Fatigue fracture on account of lowered fitting force
9）Lubrication failure and stiff backlinks as a result of deterioration and carbonization of lubricating oil
Grease fantastic in heat resistance include things like those determined by silicon, graphite or molybdenum disulfide.
For use at high-temperature, high-temperature resistance bearings and stainless steel bearings are recommended.
